Dear all,

I have an image that I need to filter, and so I'm looking for a method to
convolve it with a matrix. If I understood the docs for convolve
correctly, it only works in 1D (and I have tried to convolve, it didn't
look good).

So, I wondered if anybody have implemented 2D convolution in R, or have
any good advices to share (beyond having a look at mvfft), before I go
